따라서 순환펌프(50)의 작동시 상기 관통공(86)을 통과한 세척수는 집수통(40) 내부로 유입되어 세척기 내부를 순환하게 되고, 관통공(86)을 빠져 나가지 못한 음식물찌꺼기는 제1경사면(84)의 경사에 의해 계단형단차면(83)의 상면을 따라 삽입공(81) 측으로 안내된 후 채집필터(90) 내부에 채집된다. 그리고 이때, 상기 관통공(86)이 형성된 제2경사면(85)은 수직으로 형성되거나, 수직에 가깝도록 45도 이상 90도 이하의 경사를 갖도록 마련되는 것이 바람직한데, 이는 제2경사면(85)의 경사가 급하면 급할수록 계단형단차면(83)의 상면을 따라 채집필터(90)측으로 이동되는 음식물찌꺼기와 제2경사면(85)의 접촉이 감소되어, 제2경사면(85)에 형성된 관통공(86)에 의한 음식물찌꺼기의 간섭이 억제되기 때문이다.Accordingly, when the circulation pump 50 is operated, the washing water passing through the through hole 86 flows into the sump 40 and circulates inside the washing machine, and food wastes that do not exit the through hole 86 are first The inclination of the inclined surface 84 is guided to the insertion hole 81 side along the upper surface of the stepped stepped surface 83 and then collected in the collection filter 90. In this case, the second inclined surface 85 in which the through hole 86 is formed is preferably formed vertically or is provided to have an inclination of 45 degrees or more and 90 degrees or less so as to be close to the vertical, which is the second inclined surface 85. The steeper the steepness of the steepness, the shorter the contact between the food waste and the second inclined surface 85 which is moved toward the collecting filter 90 along the upper surface of the stepped stepped surface 83, thereby forming a through hole formed in the second inclined surface 85 ( This is because interference with food waste by 86) is suppressed.

그리고 이와 같이 경사가 급한 제2경사면(85)에 형성되는 관통공(86)은 계단형단차면(83)의 상면을 따라 채집필터(90) 측으로 이동하는 음식물찌꺼기에 대한 간섭을 최대한 억제하여, 순환필터(80)를 통해 채집필터(90) 내부로 채집되는 음식물찌꺼기의 채집이 보다 용이하게 이루어지도록 한다. 또한, 이러한 순환필터(80)를 통해 대부분의 음식물찌꺼기가 채집필터(90) 내부에 채집됨에 따라, 세척종료 후 도어(30)를 개방하였을 때, 순환필터(80)의 상면에 음식물찌꺼기가 남아 있지 않게 되므로, 세척조(20) 바닥면의 청결상태는 보다 향상된다.In addition, the through hole 86 formed in the second inclined surface 85 inclined in such a manner as to minimize the interference to the food waste moving to the collecting filter 90 side along the upper surface of the stepped step surface 83, the circulation Collection of food waste collected into the collection filter 90 through the filter 80 is made easier. In addition, since most of the food waste is collected inside the collecting filter 90 through the circulation filter 80, when the door 30 is opened after the cleaning is finished, food waste remains on the upper surface of the circulation filter 80. Since there is no, the clean state of the bottom surface of the washing tank 20 is further improved.

다음은 본 발명에 따른 식기세척기의 동작에 관하여 상세히 설명하기로 한다. 순환펌프(50)의 작동시, 우선 각 분사노즐(23,24)을 통해 식기 측으로 분사된 세척수는 낙하되며 세척조(20) 바닥에 모이게 되는데, 이러한 세척수 중 일부는 순환필터(80)의 관통공(86)을 통해 집수통(40) 내부으로 유입되고, 나머지 일부는 음식물찌거기와 함께 순환필터(80)의 계단형단차면(83)을 따라 채집필터(90) 내부로 유입된다. 그리고 제1 및 제2채집필터(91,92)의 각 필터공(91a,92a)을 통과하는 과정에서 세척수에 포함된 음식물찌꺼는 제1 및 제2채집필터(91,92) 내부에 크기별로 채집되며, 각 필터공(91a.92a)을 통과한 세척수는 상기 관통공(86)을 통해 집수통(40)으로 유입된 세척수와 함께 순환관(51)과 급수관(25)을 경유하여 다시 각 분사노즐(23,24)로 공급된후 세척조(20) 내부로 분사된다. 그리고 이러한 세척수의 순환 반복이 소정시간 이상 경과한 뒤에는 배수펌프(60)가 작동하게 되고, 배수펌프(60)의 작동에 의해 세척기 내부의 세척수는 상기 배수관(61)을 통해 세척기 외부로 배수된다. 그리고 이때, 계단형단차면(83)의 제2경사면(85)에 형성된 관통공(86)은 순환필터(80)의 상면을 따라 이동하는 음식물찌꺼기에 대한 간섭이 최대한 억제되도록 하여, 채집필터(90)에 의한 음식물찌꺼기의 채집이 보다 용이하게 되도록 한다.Next will be described in detail with respect to the operation of the dishwasher according to the present invention. When the circulation pump 50 is operated, firstly, the washing water sprayed to the table through the spray nozzles 23 and 24 falls and collects at the bottom of the washing tank 20, and some of the washing water passes through the circulating filter 80. It is introduced into the sump 40 through the 86, the remaining portion is introduced into the collecting filter 90 along the stepped step surface 83 of the circulation filter 80 together with the food residue. In addition, the food waste contained in the wash water in the process of passing through the respective filter holes 91a and 92a of the first and second collection filters 91 and 92 by sizes inside the first and second collection filters 91 and 92. Collected, the wash water passing through each filter hole (91a.92a) is again passed through the circulation pipe 51 and the water supply pipe 25 together with the washing water introduced into the sump (40) through the through hole (86) After being supplied to the injection nozzles (23, 24) is injected into the washing tank (20). After the circulating repetition of the washing water passes for a predetermined time or more, the drain pump 60 is operated, and the washing water inside the washing machine is drained to the outside of the washing machine through the drain pipe 61 by the operation of the drain pump 60. In this case, the through hole 86 formed in the second inclined surface 85 of the stepped stepped surface 83 may minimize interference with food waste moving along the upper surface of the circulation filter 80, and the collection filter 90 Make it easier to collect food waste by
